Knowledge that Transforms

This paper investigates the relation between the number of analysts following a security and the estimated adverse selection cost of transacting in the security, controlling for the effects of previously identified determinants of liquidity. Using intraday data for the year 1988, we find that greater analyst following tends to reduce adverse selection costs based on the Kyle (1985) notion of market depth. This result is consistent with the analysis of Admati and Pfleiderer (1988). Estimates of structural parameters of a version of the Admati and Pfleiderer model of endogenous information acquisition provide qualified support for the model.

We find that asset sales lead to an improvement in the operating performance of the seller's remaining assets in each of the three years following the asset sale. The improvement in performance occurs primarily in firms that increase their focus; this change in operating performance is positively related to the seller's stock return at the divestiture announcement. The announcement stock returns are also greater for focus-increasing divestitures. Further, we find evidence that some of the seller's gains result from a better fit between the divested asset and the buyer.

This paper develops a parametric family of models of generalized autoregressive heteroskedasticity (GARCH). The family nests the most popular symmetric and asymmetric GARCH models, thereby highlighting the relation between the models and their treatment of asymmetry. Furthermore, the structure permits nested tests of different types of asymmetry and functional forms. Daily U.S. stock return data reject all standard GARCH models in favor of a model in which, roughly speaking, the conditional standard deviation depends on the shifted absolute value of the shocks raised to the power three halves and past standard deviations.

This paper analyzes stock option awards to CEOs of 792 U.S. public corporations between 1984 and 1991. Using a Black-Scholes approach, I test whether stock options' performance incentives have significant associations with explanatory variables related to agency cost reduction. Further tests examine whether the mix of compensation between stock options and cash pay can be explained by corporate liquidity, tax status, or earnings management. Results indicate that few agency or financial contracting theories have explanatory power for patterns of CEO stock option awards.

This paper examines CEO pay in the banking industry and the effect of deregulating the market for corporate control. Using panel data on 147 banks over the 1980s, we find higher levels of pay in competitive corporate control markets, i.e., those in which interstate banking is permitted. We also find a stronger pay-performance relation in deregulated interstate banking markets. Finally, CEO turnover increases substantially after deregulation. These results provide evidence of a managerial talent market — one which matches the level and structure of pay with the competitiveness of the banking environment.

This paper examines empirically whether the short-swing rule (Section 16b of the Securities Exchange Act) deters managers from trading before mergers. Since a merger forces the sale of the target's outstanding equity, insider purchases within six months before the merger cannot escape this rule. We examine the 1941–1961 period when no other insider trading laws were enforced. Consistent with 16b's deterrent effect, managers' purchases drop significantly before the announcement. Before completion, the decrease occurs only in the 1941–1955 period. Surprisingly, pre-announcement sales do not decline, even though 16b cannot punish deferral of planned sales.

We document problems in measuring raw and abnormal five-year contrarian portfolio returns. ‘Loser’ stocks are low-priced and exhibit skewed return distributions. Their 163% mean return is due largely to their lowest-price quartile position. A $18-th price increase reduces the mean by 25%, highlighting their sensitivity to micro-structure/liquidity effects. Long positions in low-priced loser stocks occur disproportionately after bear markets and thus induce expected-return effects. A contrarian portfolio formed at June-end earns negative abnormal returns, in contrast with the December-end portfolio. This conclusion is not limited to a particular version of the CAPM.

A number of studies have presented evidence rejecting the validity of the Sharpe-Lintner capital asset pricing model (CAPM). Possible alternatives include risk-based models, such as multifactor asset pricing models, or nonrisk-based models which address biases in empirical methodology, the existence of market frictions, or the presence of irrational investors. Distinguishing between the alternatives is important for applications such as cost of capital estimation. This paper develops a framework which shows that, ex ante, CAPM deviations due to missing risk factors will be very difficult to detect empirically, whereas deviations resulting from nonrisk-based sources are easily detectable. The results suggest that multifactor pricing models alone do not entirely resolve CAPM deviations.

Several Eastern European countries have initiated mass privatization programs to transfer state-owned assets to the general population. We show that the decision to pursue mass privatization and even the specific design of the programs are largely dictated by politics. Nonetheless, politically feasible programs can also be made attractive from an economic standpoint in terms of maximizing value, fostering free and efficient markets, and promoting corporate governance. In general, the design of economic institutions is critically shaped by political factors, although satisfactory economic results can be achieved in spite of political constraints.

We examine the effects of trading and information flows on the short-run behavior of stock prices by comparing the behavior of stock return volatility during trading and nontrading periods. We define nontrading periods as periods when exchanges and businesses are open but traders endogenously choose not to trade. After correcting for the bid/ask bounce and stickiness in quotes, we find that a large proportion of daily stock return volatility occurs without trades, especially for large firms. Furthermore, we provide new evidence that public (versus private) information is the major source of short-term return volatility.
